METOPIOPS, new genus. 



General external characters of Masicera and Sisyropa, but with a 

 wonderful approach to the peculiar sexual head-characters of Metopia. 



Front and face in both sexes quite equilateral, m both nearly or 

 quite one and one-half times eye-width. Whole of parafrontals and 

 parafacials in male burnished silvery-white, those of female golden. 

 Both sexes with two proclinate orbital bristles, and a row of three 

 or four (usually four) reclinate ones inside them. Facialia strongly 

 ciliate, reaching nearly to second antennal joint and even with lowest 

 frontal bristles, sometimes above latter in male. Front not strongly 

 or conically produced in profile as in Metopia, but produced only 

 moderately into an obtuse angle, slightly less obtuse in male perhaps. 

 Frontalia very narrow; nearly or quite covered in middle by the 

 inward extension of the parafrontals in male, not at all so in female. 

 Face receding, vibrissse on level with the slightly produced oral mar- 

 gin, proboscis short and fleshy, palpi elongate and club-like. Eyes 

 thinly hairy in both sexes. 



Three sternopleural bristles, often a weak fourth one, in both 

 sexes. Four postsutural bristles. Two strong pairs of lateral
